Nash, a former Microsoft executive who worked on Windows for 19 years, said the level of cooperation and transparency is unprecedented, which is why the admittedly short time between the final version of Windows 10 and the on-sale date isn't a big deal.
Still, we put it in a bar chart so you could see just how little time PC vendors have.
HP would not confirm a news report that the new OS had gone "RTM," which means the final version is locked down and distributed for manufacturing. But with the official date of July 29 looming, it's clear this is Microsoft's most aggressive schedule in history. Windows 95, for example, gave PC makers 41 days to get their builds in order, and Windows XP gave makers 92 days.
If Windows 10 did indeed go "gold" or RTM today, that means PC makers have two weeks to make sure all of their drivers work and none of their applications or designs will break before going to consumers.
Nash did say HP had "everything" it needed to do its final builds, which implies Microsoft had hit its RTM milestone.
